Abstract: The clamping device (1) is divided into an upper and a  lower units (2,3), each having  the  cross-shaped  semicircular  grooves (4a,4b,4c,4d), and is formed with the concave-grooves  (7,7')  for preventing the bending of  cable  at  the  crossing  part  of  the semicircular grooves. The optical fibre cable (C)  is  clamped  by the combination of the upper and lower units (2,3). The upper unit (2) has four locking pins (5,5',5",5'")  and  center  fixing  pins (5a,5b,5c,5d) projected in integrity, and the lower  unit  (3)  is formed  with  locking  grooves  (6,6',6",6'")  and  center  fixing grooves (6a,6b,6c,6d).
